.rtf Files Virus (MegaCortex Ransomware) — MegaCortex V3 Released

A security report indicates that a new release of the Mega Cortex ransomware has been released in the wild. According to the available information this is a new version which is distinct from the previous ones. It is very possible that a new hacking group is behind it. Changes in the functionality can also be presented.

Common virus modules may be run and initiated based on the local machine conditions or specific hacker instructions. Advanced versions of such viruses will typically change important settings that can be either in the system’s base configuration files or the Windows Registry. Such changes can lead to very serious problems when using the computer in the ordinary way.

Contaminated machines might have their data stolen by running a built-in Trojan component which will establish a persistent connection to a hacker-controlled server and allow the criminals to overtake control of the computers. This will also include data theft and further issues for the victim users.

This new MegaCortex virus will mark the files that are to be processed with an unique identifier. It is probably made using data gathered by the information extracting module component. Two of the most common types of data that are hijacked include the following:

  • Personal Information — The virus can acquire data that can reveal the information about users revealing their identity and potentially using it to cause other crimes.
  • Machine Information — This will include a list of the installed hardware components.

.rtf Files Virus (MegaCortex Ransomware) – How Did I Get It and What Does It Do?

The name .rtf files virus is given to a ransomware that encodes personal files, locks them with the extension .rtf and demands a ransom fee for their recovery. Security researchers recognize it as a strain of MegaCortex ransomware. This variant is the third in a roll and like its predecessors, it causes serious damage to computers it infects.

As soon as the payload of MegaCortex v3 is dropped into the target systems the main module of the ransomware will be automatically started. This particular ransomware is designed to infect other hosts that are available on the local network. This is made possible by first running an security bypass function — the ransomware will identify if there are any installed and running software that may block the proper functioning of the .rtf files virus:

  • Anti-Virus Engines
  • Firewalls
  • Intrusion Detection Software
  • Virtual Machine Hosts and Debug/Programmer Environments

What’s more dangerous is that this updated MegaCortex ransomware version 3 can be programmed to execute a variety of other threats, especially in this case when it is directed against enterprise users.

The most likely method used for the spread of .rtf files virus is malspam. Malspam is called to spam email messages that attempt to deliver malicious software on computer systems. Such email messages are characterized by several distinctive marks. They often pose as representatives of well-known companies. Usually, contain file attachments and clickable URLs addresses. And their messages require immediate action.

The moment the attached file is opened on a target machine computer or the link is loaded in an Internet-connected browser the malicious .rtf virus payload triggers the attack with this nasty ransomware.

Once .rtf files virus applies preliminary malicious modifications it becomes able to activate a built-in cipher module by which it sets the beginning of the data encryption process. During this stage of the attack, .rtf crypto virus scans all system drives for target files and transforms their code with the help of sophisticated encryption algorithm. Unfortunately, the encryption process corrupts valuable files and limits the access to their data. Here is a list of all files that may be encrypted:

  • Audio files
  • Video files
  • Document files
  • Image files
  • Backup files
  • Banking credentials, etc

As soon as the ransomware transforms the original code of a target file, it appends the .rtf extension to its name and leaves it completely inaccessible.

When .rtf ransomware finishes the completion of malicious modifications and data corruption, it displays a ransom message on the screen. Here is what this message states:

Your companies network has been breached and infected with MegaCortex Malware.
We ensure that the only way to retrieve your data swiftly and securely is with our software.
Restoration of your data requires a private key which only we possess.
Don’t waste your time and money purchasing third party software, without the private key they are useless.
To confirm that our decryption software works email to us 2 files from random computers.
You will receive further instructions after you send us the test files.
After receiving payment we will provide you decryptor including it full source code and necessary assistance if needed.

We know that you need to restore .rtf files but be advised to refrain from transferring your money to cybercriminals. For the sake of your security, we recommend you to clean your computer from present malicious files and consider the help of alternative data recovery methods.
